Only about a month..*sigh*. Had 3 glasses of wine instead of two...Before that, it had been just over a year...Jan 31, 2011. You guessed it...champagne. Every time I've gotten sick since 1993 (when I had my last sv) has been alcohol related. And I only drink maybe once a month. If I didn't have a bit of wine now and again, I'd never be sick at all, now that I think about it.
